Passage 1In his book The Tipping Point,Malcolm Gladwell argues that"social epidemics"are driven in?large part by the actions of a tiny minority of special individuals,often called influentials,who are?unusually informed,persuasive,or well-connected.The idea is intuitively compelling,but it doesn′t?explain how ideas actually spread.The supposed importance of influentials derives from a plausible-sounding but largely untested?theory called the"two-step flow of communication":Information flows from the media to the?influentials and from them to everyone else.Marketers have embraced the two-step flow because it?suggests that if they can just find and influence the influentials,those selected people will do most of?the work for them.The theory also seems to explain the sudden and unexpected popularity of certain?looks,brands,or neighborhoods.In many such cases,a cursory search for causes finds that some?small group of people was wearing,promoting,or developing whatever it is before anyone else paid?attention.Anecdotal evidence of this kind fits nicely with the idea that only certain special people?can drive trends.In their recent work,however,some researchers have come up with the finding that influentials?have far less impact on social epidemics than is generally supposed.In fact,they don′t seem to be?required of all.The researchers′argument stems from a simple observation about social influence:With the?exception of a few celebrities like Oprah Winfrey--whose outsize presence is primarily a function of?media,not interpersonal,influence--even the most influential members of a population simply don′t?interact with that many others.Yet it is precisely these non-celebrity influentials who,according to?the two-step-flow theory,are supposed to drive social epidemics,by influencing their friends and?colleagues directly.For a social epidemic to occur,however,each person so affected must then?influence his or her own acquaintances,who must in turn influence theirs,and so on;and just how?many others pay attention to each of these people has little to do with the initial influential.If people?in the network just two degrees removed from the initial influential prove resistant,for example,the?cascade of change won′t propagate very far or affect many people.Building on the basic truth about interpersonal influence,the researchers studied the dynamics?of social influence by conducting thousands of computer simulations of populations,manipulating a?number of variables relating to people′s ability to influence others and their tendency to be?influenced.They found that the principal requirement for what is called"global cascades"—the?widespread propagation of influence through networks--is the presence not of a few influentials but,rather,of a critical mass of easily influenced people.What the researchers have observed recently shows that__________.查看材料A.the power of influence goes with social interactionsB.interpersonal links can be enhanced through the mediaC.influentials have more channels to reach the publicD.most celebrities enjoy wide media attention

Building a house costs quite a lot of money. Suppose you plan to build a house. Your first step will be to find a right piece of land. Your choice will depend on many different things. You will probably try to find a sunny place, with pleasant surroundings near shops and bus stops, not too far from your friends and the place where you work. Next you will find a good builder, and together with the builder you will work out a plan. The builder will draw the plan. It will show the number of rooms, their position and size, and other parts, which must be noticed, such as windows, doors, and electric outlets. The builder will work out how much money is needed to build your house. He will work out the cost of the wood, bricks, the glass, and everything else that must be used in building the house. Later on, when he starts to build, this estimate must be corrected and revised. His estimate is based on existing prices, but prices of such things may change, and many other things may happen between the time when he makes the estimate and the time when he builds the house. When the builder gives his estimate, you may wish to change your plan. (You may also wish to change your builder, if his estimate is too high! ) You may find that the house you wanted at first costs too much, or that you can spend a little more and add something to your plan. The builder's estimate depends on the plan, but the final plan depends on the builder's estimate. The phrase "draw a plan" in this passage means _______A.making a picture of a building or a roomB.making a planC.working out a planD.pulling a picture out of a room

Theidea is intuitively compelling, but it doesn't explain how ideas actuallyspread. The supposed importance of influentials derives from a plausible-soundingbut largely untested theory called the "two-step flow ofcommunication": Information flows from the media to the influential andfrom them to everyone else. Marketers have embraced the two-step flow becauseit suggests that if they can just find and influence the influentials, those selectedpeople will do most of the work for them. The theory also seems to explain thesudden and unexpected popularity of certain looks, brands, or neighborhoods. Inmany such cases, a cursory search for causes finds that some small group ofpeople was wearing promoting, or developingwhatever it is before anyone else paid attention. Anecdotal evidence of thiskind fits nicely with the idea that only certain special people can drivetrends. In their recent work,however,some researchers have come up with the finding that influential havefar less impact on social epidemics than is generally supposed. In fact, theydon 't seem to be required of all.The researchers ' argument stems from a simple observation aboutsocial influence: With the exception of a few celebrities like OprahWinfrey-whose outsize presence is primarily a function of media, notinterpersonal, influence-even the most influential members of a populationsimply don't interact with that many others. Yet it is precisely these non-celebrityinfluentials who,according to the two-step-flow theory, are supposed to drive socialepidemics, by influencing their friends and colleagues directly. For a social epidemic to occur, however, eachperson so affected must then influence his or her own acquaintances,who must intum influence theirs, and so on; and just how many others pay attention to eachof these people has little to do with the initialinfluential. If people in the network just two degrees removed from the initialinfluential prove resistant. for example, the cascade of change won ' tpropagate very far or affect many people. Building on the basic truth aboutinterpersonal influence, the researchers studied the dynamics of social influenceby conducting thousands of computer simulations of populations, manipulating a numberof variables relating to people's ability to influence others and theirtendency to be influenced. They foundthat the principal requirement for what is called "global cascades"---the widespreadpropagation of influence through networks—is the presence not of a few influentials but ,rather, of a critical mass of easilyinfluenced people.By citing the book The Tipping Point, the author intends to_____Aanalyze the consequences of social epidemicsBdiscuss influentials ' function in spreading ideasCexemplify people ' s intuitive response to social epidemicsDdescribe the essential characteristics of influential

For a social epidemic to occur, however, eachperson so affected must then influence his or her own acquaintances,who must intum influence theirs, and so on; and just how many others pay attention to eachof these people has little to do with the initialinfluential. If people in the network just two degrees removed from the initialinfluential prove resistant. for example, the cascade of change won ' tpropagate very far or affect many people. Building on the basic truth aboutinterpersonal influence, the researchers studied the dynamics of social influenceby conducting thousands of computer simulations of populations, manipulating a numberof variables relating to people's ability to influence others and theirtendency to be influenced. They foundthat the principal requirement for what is called "global cascades"---the widespreadpropagation of influence through networks—is the presence not of a few influentials but ,rather, of a critical mass of easilyinfluenced people.The author suggests that the "two-step flow theory"____Aserves as a solution to marketing problemsB .has helped explain certain prevalent trendsBhas won support from influentialsCrequires solid evidence for its validity
